Bulb Replacement
The headlamp is a semi-sealed beam type which uses a replace-
able halogen bulb. The bulb can be replaced from the engine com-
partment side without removing the headlamp body.
+Grasp only the plastic base when handling the bulb. Never
touch the glass envelope.
1. Disconnect the battery cable.
2. Turn the bulb retaining ring counterclockwise until it is free from
the headlamp re¯ector, and then remove it.
3. Disconnect the harness connector from the back side of the
bulb.
4. Remove the headlamp bulb carefully. Do not shake or rotate
the bulb when removing it.
5. Install in the reverse order of removal.
CAUTION:
Do not leave headlamp re¯ector without bulb for a long period
of time. Dust, moisture, smoke, etc. entering headlamp body
may affect the performance of the headlamp. Remove head-
lamp bulb from the headlamp re¯ector just before a replace-
ment bulb is installed.
Aiming Adjustment
When performing headlamp aiming adjustment, use an aiming
machine, aiming wall screen or headlamp tester. Aimers should be
in good repair, calibrated and operated in accordance with respec-
tive operation manuals.
If any aimer is not available, aiming adjustment can be done as
follows:
For details, refer to the regulations in your own country.
a. Keep all tires in¯ated to correct pressures.
b. Place vehicle and tester on one and same ¯at surface.
c. See that there is no-load in vehicle (coolant, engine oil
®lled up to correct level and full fuel tank) other than the
driver (or equivalent weight placed in driver's position).
CAUTION:
Be sure aiming switch is set to ``0'' when performing aiming
adjustment on vehicles equipped with headlamp aiming con-
trol.

NATS Audio Link/LHD
DESCRIPTION
The link with the NATS IMMU implies that the radio can basically only be operated if connected to the match-
ing NATS IMMU to which the radio was initially ®tted on the production line.
Since radio operation is impossible after the link with the NATS is disrupted theft of the radio unit is basically
useless since special equipment is required to reset the radio.
Initialisation process for radios that are linked to the NATS IMMU
New radios will be delivered to the factories in the ``NEW'' state, i.e. ready to be linked with the vehicle's NATS.
When the radio in ``NEW'' state is ®rst switched on at the factory, it will start up communication with the vehi-
cle's immobiliser control unit (IMMU) and send a code (the ``Radio Code'') to the IMMU. The IMMU will then
store this code, which is unique to each radio, in its (permanent) memory.
Upon receipt of the code by the IMMU, the NATS will con®rm correct receipt of the radio code to the radio.
Hereafter, the radio will operate as normal.
During the initialisation process, ``NEW'' is displayed on the radio display. Normally though, communication
between Radio and IMMU takes such a short time (300 ms) that the radio seems to switch on directly with-
out showing ``NEW'' on its display.
Normal operation
Each time the radio is switched on afterwards, the radio code will be veri®ed between the radio unit and the
NATS before the radio becomes operational. During the code veri®cation process, ``WAIT'' is shown on the
radio display. Again, the communication takes such a short time (300 ms) that the radio seems to switch on
directly without showing ``WAIT'' on its display.
When the radio is locked
In case of a radio being linked with the vehicle's NATS (immobiliser system), disconnection of the link between
the radio and the IMMU will cause the radio to switch into the lock (``SECURE'') mode in which the radio unit
is fully inoperative. Hence, repair of the radio is basically impossible, unless the radio is reset to the ``NEW''
state for which special decoding equipment is required.
Both Blaupunkt and Clarion have provided their authorized service representatives with so called ``decoder
boxes'' which can bring the radio unit back to the ``NEW'' state, enabling the radio to be switched on after which
repair can be carried out. Subsequently, when the repaired radio is delivered to the ®nal user again, it will be
in the ``NEW'' state as to enable re-linking the radio to the vehicle's immobiliser system. As a result of the
above, repair of the radio can only be done by an authorized Blaupunkt or Clarion representative.
Note:
Radio manufacturer of Nissan Y61 models for Europe is ``Clarion''.
SERVICE PROCEDURE
Item Service procedure Description
Battery disconnection No additional action required. Ð
Radio needs repair Repair needs to be done by authorized represen-
tative of radio manufacturer since radio cannot
be operated unless it is reset to NEW state,
using special decoding equipment.Ð
Replacement of radio by new
partNo additional action required. Radio is delivered in NEW state.
Transferring radio to another
vehicle/replacement of radio
by an ``old'' partRadio needs to be reset to NEW state by autho-
rized representative of radio manufacturer.Ð
Replacement of IMMU by
new partNo additional action required. The new IMMU will be recognized by the radio
since a `blank' code is stored in the memory of
the IMMU. In case the radio recognizes this
`blank' code, it will request for input of the correct
CATS code after which the radio will switch back
to the initialisation process.
